api 通用返回数据结构 @param request_params [Object] 请求参数 @param response [Object] 响应对象 @return [Object]
# File lib/rock_fintech/utils.rb, line 63 def self.api_result(request_params, response) { result: 'P', # 默认 request_params: request_params, response: response, flow_id: response.nil? ? nil : response.flow_id, code: response.nil? ? nil : response.data[:code], msg: response.nil? ? nil : response.data[:msg], data: response.nil? ? nil : response.data, } end

通过时间,返回唯一一个24位flow id(支持分布) 同一秒,同一台机器,同一个进程,最多可以产生 16777214 个不一样的订单号
@example
JytPay::Utils.gen_flow_id
@param time [ Integer ] 时间(默认是 now) @return [ String ]
# File lib/rock_fintech/utils.rb, line 41 def self.gen_flow_id(time=Time.now.to_i) machine_id = Digest::MD5.digest(::Mac.addr).unpack("N")[0] process_id = Process.pid % 0xFFFF @counter ||= 0 @counter += 1 count = (@counter) % 0xFFFFFF return [ time, machine_id, process_id, count << 8 ].pack("N NX lXX NX").unpack("H*")[0].force_encoding('UTF-8') end

random_key(size=16)

随机产生 size 位字符串(大小写,数字组成) @param size [Int] 需要的位数,默认 16 位 @return [String] 随机字符串
# File lib/rock_fintech/utils.rb, line 55 def self.random_key(size=16) ((0..9).to_a + ('a'..'z').to_a + ('A'..'Z').to_a).sample(size).join() end
symbolize_keys(hash)

把 hash 中的 key,都转化为 symbol 类型
@param hash [Hash] 需要更改的 hash @return [Hash] 更改后的 hash
# File lib/rock_fintech/utils.rb, line 12 def self.symbolize_keys(hash) new_hash = {} hash.each do |key, value| new_hash[(key.to_sym rescue key) || key] = value end new_hash end
